I am confused

My so and I have been having little arguments every day for about a week. We always resolve them and it never gets super serious or lasts longer than about 30 min or less. We both have one child (same age) from previous relationships and we both discussed that we want a baby together (before the bickering started). Today after sex he was like, “wait are you on birth control?” And I said no..? Obviously.

He said well you’re gonna get pregnant.

We both shrugged and went on with the night.

We had sex this morning and he finished in me (like always) and he went off to work. I said, “wait if I do get pregnant, do you want that?” Since I was obviously confused about the birth control question.

He called me and said he wants to have a baby he just wants us to not fight for at least a week— then asked me to pick up some plan b.

I’m so lost.....

So do you guys think he’s making a good choice by saying we should wait until we don’t argue for at least a week?
